Example Embodiment

[0015] The present invention will be described in detail below in conjunction with the drawings.

[0016] Such as figure 1 As shown in the structural schematic diagram of the present invention, the present invention provides an axial flow pump for online detection of bearing temperature changes, including a motor housing 1, a pump shaft 2 and a bearing seat 3. The pump shaft 2 is axially mounted on the motor housing 1. Inside, the bearing seat 3 is fixed to the bottom of the motor housing 1 by bolts, a bearing 4 is installed between the bearing seat 3 and the pump shaft 2, and a mounting hole 5 is provided on the outer side of the bearing seat 3 , A temperature sensor 6 is provided in the mounting hole 5. The mounting hole 5 is opened laterally on the outside of the housing body of the bearing housing 3.

[0017] The model of the temperature sensor 6 is PT100. The output end of the temperature sensor 6 is connected to the control end of the axial flow pump. The temperature sensor 6 is wirelessly connected to the control end of the axial flow pump.

[0018] The working process of this example: the axial flow pump provided by the present invention for online detection of bearing temperature changes, a temperature sensor 6 is installed on the bearing seat 3. The temperature sensor 6 can be as close to the bearing 4 as possible, so it can more truly reflect the actual situation of the bearing 4 Temperature, using temperature sensor 6 can detect the temperature of bearing 4 in real time, and transmit the detected temperature signal to the control end of the axial flow pump through temperature sensor 6 to achieve continuous and uninterrupted detection of bearing temperature. When bearing 4 is running abnormally, It will cause the bearing 4 to heat up, sense the temperature change of the bearing 4, cut off the main circuit, and protect the whole machine.

[0019] The mounting hole 5 is laterally opened on the outside of the housing body of the bearing housing 3, and the temperature sensor 6 is installed in the mounting hole 5. This arrangement is more conducive to saving the internal space of the axial flow pump and the installation is more compact.

[0020] The model of temperature sensor 6 is PT100, and PT100 is more sensitive in detecting temperature changes during bearing operation.

[0021] An embodiment of the present invention has been described in detail above, but the content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made in accordance with the scope of the application of the present invention should still fall within the scope of the patent of the present invention.
